Patients with severe aortic stenosis (AS) and co-existing hypertrophic cardiomyopathy (HCM), a common defect affecting the left ventricle of the heart, have been excluded from TAVR studies due to perceived challenges to optimal valve implantation in this group of patients because of the hypertrophied left ventricle that can result in an abrupt drop in afterload from a newly replaced and more efficient aortic valve. This exclusion has resulted in paucity of data on this patient population. This study aims to review outcomes in patient with HCM undergoing TAVR for severe AS.Methods: Using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement, we performed a systematic literature search of published outcomes regarding TAVR in HCM patients to provide some insight in this patient population.Results: Our study showed that TAVR had significantly lower rates of in-hospital mortality, bleeding requiring a blood transfusion, invasive mechanical ventilation, acute kidney injury, vascular complications, and decreased length of stay (LOS) compared to surgical aortic valve replacement (SAVR) in our study population of 836 subjects from 11 publications. Our study is not a randomized controlled trial, which limits its generalization.Conclusions: In severe AS patients with HCM, TAVR results in better outcomes compared to surgery.","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 1","pages":"6"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921376/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human epithelia that have received radiotherapy can also suffer from chronic wounds. Since increased expression of Cx43 was observed in murine skin following irradiation, we sought to confirm this in irradiated human neck skin because Cx43 inhibition may be a novel treatment of wounds in such tissue.Methods: We prospectively recruited adult patients who underwent elective neck surgery between November 2017 and March 2018 in the Otorhinolaryngology Department of a tertiary hospital in Singapore. A sample size of five patients with prior radiotherapy to 25 controls without radiotherapy was planned a priori. Immunohistochemical staining of Cx43 was performed in the neck skin obtained from the patients and quantified under confocal microscopy. The association between demographic factors, comorbidities of the patients, and Cx43 expression was explored. Wound healing was assessed between 7 to 14 days postoperatively.Results: Five patients received radiotherapy 9 months to 27 years before surgery. The expression of Cx43 was 94.2 vs. 146.4 pixel-area/nucleus in the epidermis with or without radiotherapy, respectively (P=0.39). The demographics and co-morbidities of the patients with or without radiotherapy were similar except for relative anemia in the patients who had radiotherapy (hemoglobin of 12.15 vs. 14.10 g/dL, P=0.02), but hemoglobin was not correlated with Cx43 expression (P=0.93). All skin incisions healed without dehiscence.Conclusions: Previous radiotherapy may not alter Cx43 expression in human neck skin. Whether the same is true for chronic radiation-induced wounds or acute radiation-induced dermatitis should be investigated.","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 1","pages":"3"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been an increasing interest in using short-term (5 minutes) HRV to identify infants ≤90 days of life with serious bacterial infections. However, there has not been any normative data range reported for short-term HRV indices in this infant population. The aim of this study was to evaluate short-term HRV indices in awake, healthy young infants >48 hours and ≤90 days of life and to establish a reference range. We also aimed to produce a clinical calculator that can be used in this population for evaluation of short-term HRV variables in young infants in the emergency department (ED) setting that can be potentially used in future clinical validation and research.Methods: We conducted a prospective observational study of short-term HRV analysis of awake, well infants ≤90 days of life in the ED setting.Results: One hundred and eight infants with complete data [51.9% male, median age 9 days (interquartile range, 4-35 days)] were included. We found that heart rate (HR) is correlated with HRV. Thus, normalisation of HRV parameters was done to remove their dependence on HR. We then provided normative reference range of widely used short-term HRV time-domain, frequency-domain, and non-linear HRV metrics in our cohort.Conclusions: We established normative values and HRV calculator for evaluation of these short-term HRV variables in young infants in ED settings that can be used for further clinical validation and clinical research.","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 1","pages":"2"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921339/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While rare, it is associated with significant challenging events for the anesthesiologist. Here we present a challenging hemicorporectomy case which was successfully managed using a multimodal anesthesia approach.Case description: The patient was a 40-year-old patient presenting for completion of a hemicorporectomy via a left hemipelvectomy for pelvic chondrosarcoma. The patient underwent hemicorporectomy under epidural and total intravenous anesthesia supplemented with ketamine and lidocaine infusion. The surgery lasted 17.5 h and resulted in 28 L of blood loss. The patient noted excellent pain control and was discharged on postoperative day 74 following an uncomplicated hospital course and in-house rehabilitation.Conclusions: Reviewing the literature, we recognized that there are no standardized anesthesia protocols published for hemicorporectomy. Based on our case report we present a novel anesthesia strategy that addresses almost all major challenges with hemicorporectomies. Our successful strategy suggests that a total intravenous anesthesia with propofol in combination with an epidural and a multimodal pain regimen with rate adjustments based on body mass reduction should be considered as a standard anesthesia protocol for hemicorporectomies. We recommend establishing a state-of-the-art anesthesia guideline for patients undergoing hemicorporectomy and encourage anesthesiologists to publish case reports describing the anesthesia approach for a hemicorporectomy.","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 1","pages":"7"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921205/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
